Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a gas-liquid separation device. Background Art
[0002] In the process of sewage treatment in sewage treatment plants, plate and frame filter presses are often needed to separate mud and water from sewage, thereby achieving sewage treatment and recovery of mud cakes, which is helpful for environmental protection and resource recovery and comprehensive utilization.
[0003] The feed of the plate and frame filter press is a mixture of mud and water. Therefore, when it stops working, the inner wall of the feed pipe is often accumulated and contaminated with sludge. If it is not treated, the sludge will become compacted and cause blockage in the feed pipe. The lumpy sludge will also affect the filtering effect and the stable use of the equipment. The equipment maintenance and overhaul caused by this will increase the overhaul and labor costs on the one hand, and also affect the normal production on the other hand.
[0004] Therefore, after the plate and frame filter press is shut down, its feed pipeline often needs to be cleaned. The existing pneumatic cleaning method is often used, that is, the sludge contaminated in the pipeline is taken out by high-speed air flow, and then discharged. However, the traditional technical means often adopt the direct discharge method. Therefore, the high-speed air flow will cause sludge to splash at the discharge port, which is not conducive to the maintenance of the factory working environment. Therefore, the utility model proposes a gas-liquid separation device to improve the above situation. Utility Model Content
[0005] The purpose of the utility model is to provide a gas-liquid separation device to achieve gas-liquid separation of the cleaning gas of the plate and frame filter press and to reduce the flow rate of the high-speed gas to facilitate direct discharge.
[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a gas-liquid separation device, including a shell, the shell is in a rectangular shape, an air inlet is arranged on one side below the shell, a baffle is arranged in the shell, a mud discharge port is arranged below the shell, and an exhaust pipe is arranged above the shell. The baffle includes a bending type located at the lower part of the shell, a multi-stage inverted V-shape arranged above the bending type, and an inclined plate type connected to the two side walls of the shell.
[0007] Furthermore, two ends of the baffle are fixedly connected to the front and rear side surfaces of the shell by welding.
[0008] Furthermore, the bent baffle includes an inclined portion and a horizontal portion, and the inclined portion is arranged opposite to the air inlet.
[0009] Furthermore, the bent baffles are arranged in one level, the inverted V-shaped baffles are staggered and arranged in seven levels, and the inclined plate-type baffles are arranged tilted downward and staggered with the inverted V-shaped baffles.
[0010] Furthermore, flushing pipes are arranged in an alternating manner with the baffle in the shell, and the flushing pipes include a flushing main pipe and a flushing branch pipe. A flushing valve is installed on the flushing main pipe. The flushing branch pipes are arranged alternately with the baffle and have multiple layers. Flushing holes are opened on the flushing branch pipes, and the flushing branch pipes flush the upper and lower sides of the baffle.
[0011] Furthermore, the top layer of the flushing branch pipes is arranged above the top layer of the inverted V-shaped baffle, the flushing holes on the top layer of the flushing branch pipes are arranged downward, and the flushing holes on the other layers of the flushing branch pipes are arranged upward.
[0012] Beneficial effects of the utility model:
[0013] 1. By setting the baffle, the mud and water in the cleaning gas can be separated from the gas, and the flow rate of the gas can be reduced to achieve direct discharge of the gas;
[0014] 2. By arranging multi-stage baffles and adopting different shapes, such as bent type and inverted V-type, the gas can be guided and blocked, so as to facilitate the separation of mud and water in the cleaning gas and reduce the gas flow rate, and the separation effect is better;
[0015] 3. Through the flushing pipe, the equipment can be cleaned regularly after the gas-liquid separation is completed to ensure the cleanliness of the equipment and thus ensure long-term and stable use. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.
[0024] Embodiments of the present utility model:
[0025] like Figure 1-5 As shown, in the gas-water separation device of this embodiment, a shell 1 is provided. The shell 1 is in a rectangular shape. An air inlet 2 is provided at the lower right side of the shell 1, a mud discharge port 3 is provided at the lower part of the shell 1, a baffle 5 is arranged in the shell 1, and an exhaust pipe 4 is provided above the shell 1.
[0026] Both ends of the baffle 5 are welded and fixedly connected to the front and rear sides of the shell 1. The baffle 5 includes a variety of shapes, including a first-level bending type 51 arranged at the bottom, the bending type 51 includes an inclined portion 511 and a horizontal portion 512 connected to the upper part of the inclined portion 511; seven levels of inverted V-shaped portions 52 arranged in an alternating manner are arranged above the first-level bending type 51; and an inclined plate type 53 connected to the left and right sides of the shell 1, and the inclined plate is arranged inclined downward.
[0027] Flushing pipes 6 are arranged in an alternating manner with the baffle 5 in the shell 1, and the flushing pipes 6 include a flushing main pipe 61 and a flushing branch pipe 62. A flushing valve 611 is installed on the flushing main pipe 61. The flushing branch pipes 62 are arranged in multiple layers from top to bottom, and multiple branches are arranged in each layer. Flushing holes 621 are arranged on the flushing branch pipes 62, wherein the flushing holes 621 on the flushing branch pipes 62 of the uppermost layer are arranged downward, and the flushing holes 621 on the flushing branch pipes 62 of other layers are arranged upward.
[0028] The principle of this utility model is:
[0029] When the utility model is in use, the high-pressure gas for cleaning the pipeline of the plate and frame filter press enters into the shell 1 from the air inlet 2, and the muddy water and the high-speed gas in the cleaning gas are separated by the guiding effect of the bent type 51 baffle plate and the blocking effect of the inverted V-shaped 52 baffle plate, and the gas flow rate can be reduced, so that the separated muddy water can be collected, and the gas with reduced flow rate can be directly discharged.
[0030] During the process of gas-liquid (mud and water) separation, the mud and water will remain in the shell 1 and be contaminated on the baffle 5. At this time, it is necessary to clean it regularly after use. The baffle 5 is cleaned with a flushing pipe 6, which can flush the mud and water from the baffle 5 and discharge it through the mud discharge port 3, thereby ensuring the long-term and stable use of the device. A control valve (not shown) is required to be installed on the mud discharge pipe connected to the mud discharge port 3. The control valve is closed during gas-liquid separation and opened during flushing.
